Triplet exciton dynamics
This project research aims to study the dynamics of exciton migration and dissociation in planar heterojunctions of organic semiconducting materials such as alpha-sexithiophene and fullerene. Time-resolved photoluminescence (PL) measurements are used to study fluorescent quenching and to evaluate the role of triplet states in the organic materials. Interfacial molecular orientations at interfaces plays an important role and thus will be also studied thoroughly. Afterwards, ultrafast transient absorption spectroscopy and PL measurements are used to investigate the dynamics of charge transfer and free-charge generation processes in the planar heterojunction thin-films with various interfacial molecular orientations. In term of the results of these measurements, new structures and devices are proposed to produce efficient OSCs.
Nong Hoang received his Bachelor degree (2014) in Engineering Physics from the Vietnam National University, Hanoi. In 2015, he got a scholarship from Erasmus Mundus Action 2 – Swap and Transfer to study a Master programme in Organic & Molecular Electronics at the Technische Universität Dresden (Germany). He completed his Master programme (2017) with the thesis carried out at the Dresden Integrated Center for Applied Physics and Photonic Materials (IAPP) under the supervision of Professor Koen Vandewal. Currently, he is a PhD candidate (ESR-2) of the Optical Condensed Matter Physics group of the Zernike Institute for Advanced Materials, University of Groningen (the Netherlands).
